I've been using Leslie's Ultra Bright Water Clarifier forever and always found it to be an excellent product. I forgot the actual chemical term, but the product caused suspended microscopic particles in the pool to clump together into larger particles that would then sink to the bottom so they could be vacuumed out of the pool. It was a very thick, viscous product that had to be stirred in a bucket to disperse it before it was broadcast into the pool. In fact, those were the specific instructions on the bottles. Now the formulation has changed. The instructions now say that the product can be directly introduced into the pool. I've been reading reviews that people now report having to use twice as much product to achieve the same result. So what happened? You know what happened. Leslie's diluted the product down. I can't see using it any more and am a bit disappointed. Do any of you use a different brand of water clarifier, one that has the same viscous properties as the old Leslie's product, and if so, are you happy with it? I would appreciate the referral. Thanks, Dave
